Jack won't start with any drivers after installing libffado

I posted this over at the Ardour forum as well, but every time I post over there they just tell me I shouldn't use Ardour/Jack with Slackware...

I installed the libffado from Slackbuilds.org yesterday on my -current box, and followed the instructions in the README for configuration. After I did that jack wouldn't start at all, insisting that there were no recognized drivers, even when I had the alsa driver selected (alsa is working fine, by the way... I have sound). After doing some more research I uninstalled jack and built Jack2 (1.9.6) from source with the following configure options:

Code:

./waf configure --firewire --alsa --dbus --enable-pkg-config-dbus-service-dir

Now when I try to launch jack (regardless of selected driver) I get the following message in qjackctl:

Code:

21:05:32.183 JACK is starting...

21:05:32.183 /usr/local/bin/jackd --no-realtime -r -dalsa -dhw:0 -r48000 -p1024 -n3

21:05:32.185 JACK was started with PID=30359.

Are you sure this is related to installing ffado? Ie, does removing ffado and recompiling jack without it fix the issue?

Removed Jack2 and libffado, reinstalled Jack1. Still won't start, but new error message:

Memory locking is unlimited - this is dangerous. You should probably alter the line:

    @audio  -  memlock    unlimited

in your /etc/limits.conf to read:

This is maddening. It worked fine until I installed libffado.

This looks like you built jack against celt, but it's not installed on your current system. Try installing that and see if it works then.
